At NASA's Washington headquarters on Monday, a panel of space program scientists announced their estimation that humans will find extraterrestrial life within 20 years, going as far as to say that the estimate is a "conservative" one.

NASA outlined its plan to search for alien life and said it would launch the Transiting Exoplanet Surveying Satellite in 2017. The agency predicts that as many as 100 million worlds in the Milky Way galaxy may be home to alien life.

"Just imagine the moment when we find potential signatures of life," Matt Mountain, director of the Space Telescope Science Institute in Baltimore, said at the announcement. "Imagine the moment when the world wakes up and the human race realizes that its long loneliness in time and space may be over — the possibility we're no longer alone in the universe."

NASA astronomer Kevin Hand seconded Mountain's opinion, saying that within the next 20 years, "we will find out we are not alone in the universe," suggesting that extraterrestrial life may exist on Jupiter's moon Europa. The scientists at the panel said NASA's efforts are focusing on finding alien life on planets or stars outside the Earth's solar system.

Unusually catastrophic monsoon rains continued Saturday in the southern Indian state of Kerala, where more than 300,000 people have now evacuated their homes to escape rising floodwaters. Another 10,000 are thought to be trapped on their roofs awaiting rescue.

Severe flooding has lasted for more than a week, and at least 324 people have died in connection to the floods. More rain is expected at least through Monday, hindering already fraught rescue efforts. Nevertheless, 82,000 rescues were completed on Friday alone.

"It's a four-story house, but water started pouring in fast until it reached the second floor and stayed that way for two days," said one woman named Shrinni, who lives with her family in a town called Ranni. "My relatives shifted to the top floor with all the stuff they immediately needed. An airlift came, but as my 85-year-old grandmother had never taken a flight in her life and she was afraid to go. So the whole family stayed back. On Friday, rescuers came with motor boats and shifted them to a safe place." Bonnie Kristian

President Trump this week revoked security clearance for former CIA Director John Brennan, and Saturday morning he continued his feud with Brennan on Twitter:

The tweet may have been prompted by an interview Brennan gave on MSNBC Friday night. "The fact that [Trump is] using a security clearance of a former CIA director as a pawn in his public relations strategy I think is so reflective of somebody who is drunk on power," Brennan told host Rachel Maddow. "I think he's abusing the powers of that office."

Brennan argued Trump's decision "flies in the face of traditional practice, as well as common sense, as well as national security." The former CIA director's cause has been supported by a dozen former U.S. intelligence chiefs; Trump meanwhile, reportedly intends to revoke other people's security clearances, too. Bonnie Kristian

Police in Weld County, Colorado, northeast of Denver, on Thursday found the bodies of Shannan Watts and her two daughters, Bella, 4, and Celeste, 3. Watts was pregnant with her third child.

The family members are believed to have been killed by their husband and father, Chris Watts, who has been arrested but not yet formally charged. He reportedly confessed to the crime after his arrest and is expected to face murder charges by Monday.

The bodies were found on the property of a petroleum and natural gas exploration company where Chris used to work. Court documents filed Friday suggest strangulation may be the cause of death. Bonnie Kristian

The weapon used in the Saudi-led coalition airstrike on a school bus in Yemen earlier this month that killed 51 people, 40 of them children, and wounded over 100 more was manufactured in the United States, CNN reported Friday night.

The bomb in question was reportedly a 500-pound laser-guided MK 82 bomb produced by Lockheed Martin, an American defense contractor. It was identified from numbers on the shrapnel.

The Saudi coalition, which has been credibly accused of war crimes in Yemen, is supported and enabled by the United States. The coalition promised to investigate itself for this attack.

A coalition representative declined to comment on the airstrike while the self-investigation is underway, and a Pentagon representative would not confirm the bomb's origin, instead providing CNN a generic condemnation of civilian casualties. Bonnie Kristian

Former United Nations Secretary General Kofi Annan died Saturday after a brief illness, his family reported via his personal foundation. He was 80 years old.

Born in Ghana in 1938, Annan began work at the U.N. in 1962, rising through the ranks to serve as secretary general from 1997 to 2006. He shared the Nobel Peace Prize with the U.N. in 2001.

Current U.N. Secretary General Antonio Guterres said Annan "provided people everywhere with a space for dialogue, a place for problem-solving, and a path to a better world." Annan is survived by his wife and three children. Bonnie Kristian

Special Counsel Robert Mueller is seeking a short prison sentence of up to six months for former Trump campaign adviser George Papadopoulos, who allegedly delayed federal investigators by lying to them.

"[Papadopoulos'] lies undermined investigators' ability to challenge the Professor or potentially detain or arrest him while he was still in the United States," Mueller's team said in court filings Friday. "The defendant's false statements were intended to harm the investigation, and did so."

The "Professor" in question is Joseph Mifsud, who reportedly has ties to the Russian government and contacted Papadopoulos offering "dirt" on Hillary Clinton during the campaign. Papadopoulos pleaded guilty to lying about Mifsud to the FBI in October.

Papadopoulos and his attorney could not be reached by Wall Street Journal requests to comment on the possible jail time, but Simona Mangiante Papadopoulos, George's wife, has been publicly asking President Trump to pardon him. Bonnie Kristian

President Trump on Saturday alleged on Twitter, to his 53.8 million followers, whom he reaches for free via the network's platform, that social media is censoring the right:

In follow-up tweets, the president spun a confusing and contradictory approach to censorship, apparently speaking in response to conspiracy-monger (and Trump fan) Alex Jones' internet woes:

So, to summarize: Social media is censoring Republicans, and our Republican president is letting us know via social media. Censorship cannot be policed, but the Trump administration won't let it happen! Trump himself deplores censorship and thinks everyone should speak in the public square, but he definitely would prefer to censor CNN and MSNBC, who are "Fake News" and would ideally be weeded out. Got it? Bonnie Kristian
